hey Alexander, Thanks for the reply. Unfortunately, IHTMLDocument::navigate and IHTMLWindow::navigate don't support specifying the target frame. They only take the URL as a parameter. Also, they don't have a navigate2 function. IWebBrowser does. I think I might have something else going on here though, so I'll just have to look at it some more. Any other suggestions would be great though. Thanks.

You quite right, I must have misread your original post. You still might check the pages for the default frame, though I think I agree with you that there is probably something else going on. When you say it opens a new window, do you mean a new IExplorer window?
Sorry for the mistake, I'll see if I can figure anything else out.
Sincerely,
Alexander Wiseman

Right, It opens a new Internet Explorer window. I haven't been able to check yet, but it's possible that I'm getting a different href than I think. In that case, I could possibly be passing a javascript call into navigate that might be opening a new window...but it's so weird that it's only doing this on IE 5.0 and not on later versions. hmmm...I'll keep looking. Thanks for your help.

Hi,
I'm new to COM programming and in need of a little help. I'm trying to test some DirectX Filters which are COM objects and have done the following:
I took a DirectX interface called IAMTVTuner and renamed it IAMTest. I want to see if it will still work under it's new name because I am going to end up doing some funky things with it. The problem I think is that the GUID is still associated with IAMTVTuner. I'm not sure how to either: associate the GUID with the IAMTest OR give the IAMTest a new GUID.
Is the association of GUIDs with COM objects and interfaces done in .idl files? I tried running Midl.exe on a file that I changed but I get errors. I'm not even sure if I'm on the right track.
Thanks

I want to use my interface pointer in new thread and this component is written by pure C++ not using ATL or MFC,my codes as below:
const CLSID clsid={0x7D519042,0x1645,0x4a8c,{0xBD,0xE0,0x0F,0x4A,0x44,0xFC,0x38,0xC4}};
const IID iid1={0x7D519040,0x1645,0x4a8c,{0xBD,0xE0,0x0F,0x4A,0x44,0xFC,0x38,0xC4}};
HRESULT hr=CoInitializeEx(NULL,COINIT_APARTMENTTHREADED);
if(FAILED(hr))
{
MessageBox("CoInitialize Failed");
CoUninitialize();
return;
}
ISimpleInterface* ptr1=NULL;
hr=CoCreateInstance(clsid,NULL,CLSCTX_INPROC_SERVER,iid1,(void**)&ptr1);
if(FAILED(hr))
{
HLOCAL buf=NULL;

ptr1->Release();
CoUninitialize();
How to modify that error,Using functiong of RpcServerRegisterIf2 to Register??? I don't know what to do next,please help me,thanks a lot

After much research I believe the function CreateObjrefMoniker will solve my problem.
When I look in objbase.h I find this is missing so my project will not compile.
How can I use this function.
Using Visual C++ 6.0 SP5 and MFC

I'm trying to print an HTML file using AxWebBrowser.ExecWB in a C# app but it gives a run time error "Trying to revoke a drop target that has not been registered". Does anyone have any suggestions?
axWebBrowser1.QueryStatusWB(SHDocVw.OLECMDID.OLECMDID_PRINT);
object o = "";
SHDocVw.OLECMDID Print = SHDocVw.OLECMDID.OLECMDID_PRINT;
SHDocVw.OLECMDEXECOPT PromptUser = SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_PROMPTUSER;
axWebBrowser1.ExecWB(Print, DontPromptUser, ref o, ref o);
Thanks.

Hi All,
It seems when using attributed COM object in VC7, defaultvalue parameters do not work correctly in late-binding environment.
Asseme I have a method:
[id(1), helpstring("method AA")] HRESULT AA([in, defaultvalue("1")] LONG abc);
In VBScript, I can call it as:
Object.AA 1
but can't use shorter syntax:
Object.AA
If the same method is declated in non-attrbited library (i.e. separate IDL and H file), all works fine. Also, all works fine when early-binding is used in VB6.
I tried to add optional attribute to method, oleautomation and nonextensible to class, but all of this does not help.
Of course, it's possible to forget attributes and write old-style separate IDL/H objects, but it does not seem to be graceful solution.
Regards,
Alex

I need someone to help me understand temp files created for Word documents. I have visited the link http://support.microsoft.com/support/kb/articles/Q211/6/32.asp
and I have a broad understanding that the ~WRO temp files are Ole Object files. I am using the DSO framer OCX from Msft that can open Active documents. I am tweaking the DSO framer such that Word docs are opened as read-only when viewed in the DSO Framer. I have automated keyboard and menu events such that the document is read-only and content cannot be copy-pasted and so forth. However in the TMP folder I see this ~WRO tmp file that any user can access and copy content from, even though the DSO framer shows the file as read only. I need to program the DSO framer such that this temp file cannot be accessed or is hidden.
I would also like to mention that my version of the DSO framer is not required to allow users to modify displayed documents or save them.
How can I (by automating Word or by modifying my OLE code) transfer data to the local server without creating this ~WRO tmp file ?
I will really appreciate help on this.
Thanks,
Vishal More

Hello everyone,
I was wondering if it would be a good idea for a thread starter to indicate in his first post, wether his problem was solved, by editing the said post and appending "<-- solved" and the end of the post subject.
Just think it would be nice, and would allow for 2 things:
1) avoid replying to someone that doesnt need an answer anymore. Of course this doesnt mean that you can't add new comments to a solved problem.
2) we could see if what someone suggested did solve the problem and therefore, it could answer someone else having a similar problem.
What do you think guys ?

I want to use the pointer of an Interface in the other thread,so I have Marshalled my interface in the main thread,my codes as below:
HRESULT hr=CoInitializeEx(NULL,COINIT_APARTMENTTHREADED);
if(FAILED(hr))
{
MessageBox("CoInitialize Failed");
CoUninitialize();
return;
}
const CLSID clsid={0x7D519042,0x1645,0x4a8c,{0xBD,0xE0,0x0F,0x4A,0x44,0xFC,0x38,0xC4}};
ISimpleInterface* ptr1=NULL;
hr=CoCreateInstance(clsid,NULL,CLSCTX_INPROC_SERVER,iid1,(void**)&ptr1);
if(hr)
{
MessageBox("CoCreateInstance ISimpleInterface Failure");
return ;
}
hr=CoMarshalInterThreadInterfaceInStream(iid1,ptr1,&pStream);//Failure:
if(S_OK != hr)
{
ptr1->Release();
MessageBox("CoMarshalInterThreadInterfaceInStream Failure");
return ;
}
DWORD dwThreadId=0;
CreateThread(0,0,ThreadFun,0,0,&dwThreadId);
hr=ptr1->Sum();
if(FAILED(hr))
{
ptr1->Release();
MessageBox("DoSimpleMsgBox Failure");
return ;
}
ptr1->Release();
CoUninitialize();
I have looked up the error code,it interprets that I don't registered the UI,now how do I register it?
thanks a lot

Hello,
I am trying to instantiate an ActiveX object. However, I am having some problems with threading. When I try to instantiate it without any threading statements, as follows:
public static void Main(String[] args) {
Application.Run(new SetupCreator());
}
public SetupCreator() {
ESRI.MapObjects2.Core.AxMap map1 = new ESRI.MapObjects2.Core.AxMap();
/*....*/
this.Controls.Add(map1);
}
I get the exception: "Could not instantiate ActiveX control '9bd6a64b-ce75-11d1-af04-204c4f4f5020' because the current thread is not in a single-threaded apartment." So, I did some research, and added the line
[STAThread
to just before main. With that there, I get "There is no source code available for the current location". I found another approach, which adds the line:
Thread.CurrentThread.SetApartmentState(ApartmentState.STA);
and getting rid of the STAThread line. Now, with this in place, I get "Failed to set the specified COM apartment state." So, I am a little lost as to what to do. Any suggestions?

I have a need to implement a scheduler to automate running our COM+ application. Before I started building my own, I thought I would check if anyone has already created an app that they are willing to share.
Thanks,
Kevin

I forgot to mention that each COM+ application needs to start in it's own thread.

Hi, I'm a vb6 programmer and want to learn COM programming. My previouse experience is working vb6 and database (such as access or sql server). I want to learn COM by using vb6 programming language. I would like to ask you two questions:
1. Is it possible to learning COM with vb6 programming language? I don't like to use c++, I prefer vb6 because it is easier.
2. Are there any resource to learn COM programming from the beginner?
Please give a comment or suggestion to me

Hi ,
U can learn COM programming using VB6 itself. but to understand COM in depth , u need to learn it in C++ . VB hides lot of details from u.
There is something called ActiveX DLL and ActiveX projects in VB6. if u create an ACtiveX DLL or ActiveX EXE project, and write a VB6 class module,
ur one ur way to create a COM object. One can invoke the classes u created in VB6 from C++ or Delphi.
To understand COM in VB , Try to learn what implements keyword does. Try to
read as much as possible. Then there are things like
Automation and IDispatch interface
Dual interface
Explore what is the difference between
Dim x as new ADODB.Command
and
Dim x as object
set x = CreateObject("ADODB.Command")
if u want to create COM objects for ASP which should run at the session scope , ur out of luck with VB. But , if u learn all about implements keyword , writing aDdins etc , u will have good overview of COM.
There is a book by Apress by the name VC++ for VB Programmers . Try to read it .
Hope this helps

Thank you very much for your idea. I'm fimilar with VB6 but very difficult to learn c++. I used to learn c++ but it seem that it is a very difficult programming than vb6. What I want to do is working with COM programming more deeply with vb6. Thank you very much for your advices!!

VB6 programming language entirely may develop COM ,but also simple and quickly. The resource really is not a problem to a programmer , the network is so large , and takes a little time then you 'll gain a lot of infomation.
thank u

What is the best way to get an IStream interface pointer on an existing file? I am using Visual C++ 6.0.

AFAIK, there is no known implementation for files. I implemented it myself, which is pretty straight forward.

I found the SHCreateStreamOnFile function. Was wondering if there was somthing in the STG group of functions that I could use.

Hey, thanks for the function. I haven't seen it before, and certainly not in the STG headers.
